Fig. 1 is a flow chart of an embodiment of the transplanting method of xanthoceras sorbifolia seedlings in desert soil.
Referring to fig. 1, the method for transplanting xanthoceras sorbifolia seedlings in desert soil of the present embodiment specifically includes the following steps:
s101: and irrigating the desert soil, and performing hole-shaped soil preparation and digging planting pits.
The desert soil, also called aeolian sand soil, is soil developing in aeolian sandy parent substance, and is mainly characterized in that the mineral part of the soil almost consists of fine sand particles (the diameter is 0.25-0.05 mm), the section hierarchical differentiation is not obvious, only an A layer (eluviation layer) and a C layer (parent substance layer) lack a B layer (deposition layer), the wind erosion is serious, and the soil is in a juvenile stage. The desert soil is coarse, fine sand grains account for more than 80-90% of the weight of mineral parts of the soil, and the contents of coarse sand grains, powder sand grains and sticky grains are very small. Drought is another important property of desert soil, the surface layer of the soil is mostly dry sand layers with different thicknesses, generally about 10-20 cm, and the water content below the soil is only 2-3%. The organic matter content is low and is in the range of about 0.1-1.0%; there is an accumulation of salt, which is carried away from the site by the wind, and calcium carbonate, which is the result of decomposition of plant residues and deposition of dust.
Generally, the plantation of the shinyleaf yellowhorn seedlings is mostly selected in spring, particularly in the late 3 th to the early 4 th of each year, and desert soil zones are windy in spring, so that the plantation of the shinyleaf yellowhorn seedlings is mostly carried out by selecting land blocks which are relatively sheltered from wind and face the sun.
Before transplanting, desert soil needs to be irrigated and hole-shaped soil preparation is carried out to dig planting pits, so that transplanting and planting of the shiny-leaved yellowhorn trees are facilitated.
Wherein, the size of the planting pit is preferably 35cm multiplied by 35cm, namely the length of the planting pit is 35cm, the width of the planting pit is 35cm, and the depth of the planting pit is 35 cm; meanwhile, the distance between the planting pits is also limited, namely the plant spacing of the planting pits is 1.5m, and the row spacing of the planting pits is 1.5m, namely, after the xanthoceras sorbifolia seedlings are planted, the plant spacing and the row spacing of the xanthoceras sorbifolia seedlings are respectively 1.5 m.
S102: and after soaking the roots of the shinyleaf yellowhorn seedlings, planting the shinyleaf yellowhorn seedlings into the planting pits.
Wherein, the root neck of the shinyleaf yellowhorn seedling is buried in the desert soil for 5-10 cm.
Before planting the shinyleaf yellowhorn seedlings in the planting pits, the roots of the shinyleaf yellowhorn seedlings need to be soaked, so that a large amount of water is absorbed by the roots of the shinyleaf yellowhorn seedlings, and the survival rate and the fruiting rate of the shinyleaf yellowhorn seedlings are increased.
After long-term research of the inventor, when the soaking treatment is carried out, the treatment solution of the invention is preferably an aqueous solution of rooting powder, and the soaking treatment time is 1-2 days, namely, before the shinyleaf yellowhorn seedling is planted in the planting pit, the root of the shinyleaf yellowhorn seedling is soaked in the aqueous solution of the rooting powder for 1-2 days, and planting is carried out after the root of the shinyleaf yellowhorn seedling absorbs enough nutrient components and water. In the treatment fluid of the present invention, the mass ratio of the rooting powder to water is 1: 500.
After the soaking treatment is finished, the shinyleaf yellowhorn seedlings can be planted. In planting, the invention is different from the method that the root of the shinyleaf yellowhorn seedling is enhanced in ventilation by exposing the neck of the root of the shinyleaf yellowhorn seedling to the ground surface so as to promote the shinyleaf yellowhorn seedling to survive, and the invention innovatively buries the root and the neck of the shinyleaf yellowhorn seedling in a planting pit and covers desert soil, and particularly, the planting depth is 5-10cm when the neck of the shinyleaf yellowhorn seedling is buried in the soil. Because the planting season has the characteristic of strong wind and much wind, if the root system of the sapling is planted too shallowly, the root system of the sapling is exposed on the surface of sandy soil after being blown by strong wind, so that the sapling loses water and is dried up, and the death rate is too high. In addition, when the seedlings are planted, the seedlings need to be righted, the root systems are stretched, root nesting is avoided, and finally sandy soil is compacted.
In the invention, high-quality shinyleaf yellowhorn seedlings with the seedling age of 1 year are selected for transplanting.
S103: and (4) irrigating the shinyleaf yellowhorn seedlings with the first drop of water until the shinyleaf yellowhorn seedlings survive.
Wherein the frequency of the first drop of water irrigation is 2 h/day, and the dropping speed of the first drop of water irrigation is 6L/h.
And after planting the shinyleaf yellowhorn seedlings, carrying out first drop irrigation operation on the shinyleaf yellowhorn seedlings. Specifically, a drip irrigation device with water dripping ports is paved on the desert soil, each water dripping port corresponds to one shinyleaf yellowhorn seedling, water is infiltrated into the desert soil through water dripping of the water dripping ports, and therefore the water is absorbed by the roots of the shinyleaf yellowhorn seedlings.
Because the water resource in the desert soil environment is short and the sunshine time is long, the invention adopts a drip irrigation mode rather than a watering mode. The drip irrigation mode can save water and reduce water evaporation to prevent sand water loss. The inventor finds that when the drip irrigation duration and the drip speed are controlled, the normal growth of the seedlings can be guaranteed, the phenomenon that the roots of the seedlings are likely to be rotten due to water immersion can be avoided, and specifically, the first drip irrigation frequency can be controlled to be once a day, 2 h/time and the drip speed is 6L/h.
In addition, the drip irrigation operation in the first year can be kept until the seedlings survive, namely, the drip irrigation operation can be stopped after the seedlings of the shinyleaf yellowhorn survive in the second year of transplanting.
And after the transplanted shinyleaf yellowhorn seedlings survive in the second year, carrying out second drip irrigation on the shinyleaf yellowhorn seedlings by reducing the drip irrigation frequency, wherein the second drip irrigation frequency is 1-3 times a week and 2 h/time, and the drip speed of the second drip irrigation is 6L/h.
It should be noted that, in order to ensure that the shinyleaf yellowhorn seedlings can be prevented from being frozen by wind in the first year of planting, in the middle of 11 months of the first year of planting, the shinyleaf yellowhorn seedlings need to be subjected to one-time water dripping overwintering, and the one-time water dripping time is specifically controlled to be 6 hours, and the water dripping speed is 6L/h.
S104: and (4) topdressing the xanthoceras sorbifolia seedlings before the xanthoceras sorbifolia seedlings in the second year germinate.
Before the shinyleaf yellowhorn seedlings are planted and germinate in the spring of the next year, topdressing can be carried out on the shinyleaf yellowhorn seedlings, so that the healthy growth of the shinyleaf yellowhorn seedlings is ensured.
When the top dressing operation is carried out, the ternary compound fertilizer is preferably selected. In the invention, the ternary compound fertilizer is a chemical fertilizer with the total nutrient of more than or equal to 45 percent and the mass percentage content of nitrogen, phosphorus pentoxide and potassium oxide of 15 percent respectively.
According to the transplanting method of the shinyleaf yellowhorn seedlings in the desert soil, the survival rate of the shinyleaf yellowhorn seedlings in the desert soil is remarkably improved to over 90% by limiting the planted forest land, the land preparation mode, the root pretreatment before planting, the planting depth, the irrigation mode and the later management, and the fruit bearing rate of the shinyleaf yellowhorn seedlings is ensured to be over 90%, so that the ecological significance of the shinyleaf yellowhorn seedlings in maintaining the water and soil treatment environment in the desert soil can be exerted, and the economic benefit of the shinyleaf yellowhorn can be obtained by processing the shinyleaf yellowhorn into products.
